Haha, yeah, I titled it "Rattman's Cave" and then laughed and put "RattCave" in the description because I couldn't get that joke out of my head. It's too perfect-sounding. Glad someone else found it amusing. : )

Someone is making a game that fills in the story between Portal and Portal 2. It will have new characters and non-linear plot , according to summary, as well as some new technology. Hope it'll turn out to be good. Valve let them make it since they're making it free and all. The demo is supposed to be out sometime this summer, and the game in 2015.
